Similar reference characters indicate corresponding parts throughout the severalvie s in the drawings.

Referring to the drawings in detail, the machine comprises a stand A having the upright legs ill, these being secured to a foundation II in their vertical upright position and support a table or bed l2 disposed horizontally and at the front portion thereof is arranged a mold carriage 13 having opposite side arms l4 which are pivoted at iii to the table or bed l2 for vertical swinging movement. This carriage l3 has rotatably associated therewith a chuck it formed with opening and closing jaws |1 adapted for embracing and securing in place a blown glassware article l8 having the stem l9. The jaws l1 are fitted in a circular head 28 at the upper end of a turning shank 2| for the said chuck l6 which is suitably rotatably supported in the bed l2 and within this shank 2| is a spring tensioned jaw opener and closer in the form of a plunger 22 for actuating the Jaws H of the chuck H5 in the clamping and unclamping of the glassware |8 in a manner presently described.

Suitably supported in the stand A is an electric motor 23 which is immediately beneath the table or bed I 2 and its power shaft 24 through gear connections 25 operates a drive shaft 26 extended within a transmission case 21 fixed within the stand A. Within this case is transmission mechanism 28 controlling a driven shaft 29 which also extends into the case 21, these shafts 26 and 29 being fitted in bearings or hangers 38 in the stand A. The driven shaft 29 carries a beveled pinion or gear 3| meshing with a companion gear 32 fixed to the shank 2| so that motion can be imparted to this shank for the turning of the chuck l6. The transmission mechanism 28 is of a type to effect rotation of the shank 2| or oscillation thereof and such mechanism is susceptible of a neutral position to render the shank 2| and its chuck |6 passive, the mechanism 28 being controlled through manually set handle 33 connected through linkage 34 therewith and this handle is located at the front of the stand A convenient to an attendant of the machine.

Pivotally supported in the stand A is a throw lever 35 having the contact end 36 operative upon the plunger 22 so that when this lever 35 is depressed the jaws H of the chuck |6 will be opened for the reception of the glassware |8 for the clamping of the same; the jaws being closed under the influence of a spring 31 active upon said plunger 22 within the shank 2| when pressure is removed from the lever 35 and such lever is manually operated.

The handle 33 cooperates with a dial 38 at the front of the sand A indicative of rotary, neutral and oscillatory set positions of the transmission mechanism 28.

The carriage |3 has a step 39 above which rises a vertically disposed hinging post 40 extending perpendicular and having loose thereon a pair of reversely extended links 4| which also are loosely engaged with vertical shift posts 42, the post 40 being fixed in the step 39 and such shift posts 42 are at opposite sides of the latter and uniformly spaced therefrom. These posts 40 and 42 are extended upwardly uniformly to a determined height from the step 39 of the carriage |3. The post 48 is provided with external screw threads 43 for a purpose presently described.

Fitted upon and suitably guided on the table or bed I 2 'beneath the step 39 of the carriage I3 is a slide 44. having a releasing socket or seat 45 for a coupling pin 46 movable in a guide slot 41 in the step 39 of the carriage 3 and pivotally connecting a pair of throw links 48 loosely attached with the posts 42 so that when the slide 44 is shifted the said posts 42 will also be shifted by the throw links 48. The slide 44 is shifted by a compound lever including the member 49 pivoted at 58 to the said slide 44 and at 5| to the other member 52 of said lever and this member 52 constitutes a hand crank pivoted at 53 to the table or bed l2, the member 49 when in one bers 49 and 52 is located at one side of the stand A preferably at the right hand side thereof. The shifting of the slide 44 by the compound lever including the members 49 and 52 is for a two-fold purpose hereinafter fully described.

Operatively carried by the posts 48 and 42 at a determined elevation above the chuck H5 is the foot or base molding or forming mechanism for the stem glassware 8 and comprises a pair of horizontally arranged opening and closing arms 54 and 55, respectively, hinged on a sleeve 56 loose upon the post 48 While carried by this post are nuts 51, these being adjustable through the threads 43 on said post and lock the sleeve 56 in an adjusted position upon the latter to locate the arms 54 and 55 at the determined height above the chuck |6. The arms 54 and 55 are formed with eyes 58 loosely receiving the shift posts 42. These arms 54 and 55 through extensions 59 are formed with mold supports 68 disposed in a horizontal plane and match each other when brought toward one another. On these supports 68 are mold racks6l, one being fixedly pivoted at 62 and the other displaceably pivoted at 63, respectively. These racks 6| in their pivotal mounting, which is at the inner ends thereof, are susceptible of being variably inclined reversely to each other and the set inclined position of such racks will be had by set screws 64 threaded in the supports 60 close to the outer ends thereof. The racks 6| have thereon carbon mold units 65 and 66, respectively, the unit 65 being formed with an edging ledge or shoulder 61 and such units are made fast to the racks 6| by releasable clamping straps 68 fastened at 69 in place on the racks 6| and in this manner the units 65 and 66 are removable from the racks.

The racks 6| and the units 65 and 66 at the approaching edges thereof are provided with half circular recesses 10 for the accommodation of the stem IQ of the glassware 8 on the bringing together of the supports 60 and the snug fitting of the units 65 and 66 about said stem for a purpose presently described.

Formed on the arm 55 are bearings 1| in and between which is pivoted at 12 a vertically swinging hanger 13 provided at its lower face with a pivot ear 14 fitted with a pivot 15 for swingingly connecting a rocker head 16 therewith. This rocker head 16 through a pivotal connection 11 carries a mold rack 18 in which is removably fitted an upper carbon mold unit 19. The head 16 has the lateral extension 88 for the rack 18 so as to properly position the unit 19 for coworking with the units 65 and 66 when these units are in closing relation to each other for the molding or formation of a base or foot of glass to the ware |8 at the stem l9 thereof in the operation of the machine.

The hanger 13 carries a pair of spaced set screws 82 which play against the head 16 for setting the same level or at an incline in either a forward or rearward direction. The head 16 carries a pair of spaced set screws 8|, these acting against the rack 18 to regulate the swing thereof on the pivotal connection 11 while this rack has formed therewith a lateral ear 83 in which is a set screw 84 adapted for contact with a clamping strap 68 to dispose the unit 19 at an inclination when closing the mold units for the molding or casting of the foot or base 85 of glass upon the stem 9 of the ware l8 in the operation of the machine. Interposed between the head I8 and the rack I8 at one side of the pivotal connection 11 therebetween is a coiled spring 88 which functions for urging the rack in a direction for the contact of the set screw 84 with the strap 88 next thereto when the mold units are closed. The rack I8 is in a limited degree self-adjusting on the closing of the unit I9.

Formed on the arm 55 is a bearing 81 in which is journaled a rocking shaft 88 'to which is fixed a hand lever 89 having connected thereto a coiled retractile spring 98 fixed to a holding pin 9| in the support 88 next thereto and this spring effects the automatic opening of the unit I9, the shaft 88 being fitted with a crank 92 to which is pivoted a link 93, the same being also pivoted to the hanger I3 and in this manner on the rocking of the shaft 88 motion will be imparted to the unit I9 for vertical swinging movement to opened or closed position.

The shaft 88 carries a cam or eccentric 94 active upon a pivotally supported presser lever 95 carrying an adjustable set screw 98 which is adapted for engagement with a contact 91 on the rack 8| next thereto so as to dispose such rack at a determined inclination and to shift it toward the other rack 8| carrying the unit 85 when the mold units are closed with respect to each other and in this fashion having the units 85 and 88 snugly embrace the stem I9 of the ware I8 and assuring the proper. bevel to the base or foot 85 in the forming thereof of glass.

The spring 98 when down pressure is relieved from the lever 89 will automatically open the unit I9 while the arms 54 and 55 will be caused to swing to open position of the units 85 and 88 laterally through the action of the shifting of the posts 42, the said slide 44 in movement thereof being for this purpose. The slide 44 also shifts the posts 42 to close the arms 54 and 55 for the bringing together of the units 85 and 88 in molding position with respect to each other for the molding of the glass foot or base 85. It is understood, of course, that a determined quantity of molten glass as at 91:: is placed upon the units 85 and 88 when closed at the point of location of the stem I9 of the ware I8 to enable the formation of the base or foot 85, it being understood,

of course, that the unit 19 will be in open position y when this quantity of molten glass 91a: is placed upon the units 85 and 88 as is clearly shown in Figure 11 of the drawings.

Pivoted to a bracket 98 on the stand A is a hand lever 99 which through the link I88 pivoted thereto and to the carriage I3 enables through hand manipulation of the lever 99 the vertical swinging of the said carriage I3 and when this carriage is swung upwardly and outwardly it enables the mold units 85, 88 and I9 to be dipped in a cooling liquid such as water for the rendering of such units cold, it being understood, of course, that this is effected after the foot or base 85 has been molded or formed on the stem I9 of the ware I8 and the latter removed from the machine. Normally the carriage I3 is lowered onto the table or bed I2 to assume a horizontal position and when such carriage has been raised for the tilting thereof the slide 44 will have been shifted to permit the release of the pin 48 from the latching seat 45 in said slide 44, the pin 48 being latched to the slide 44 when the mold units 85 and 88 are shifted toward each other in the lateral closing of the same. The closing of the units 85 and 88 is independent of the closing of the unit 19 which is accomplished by manually operating the lever 89. To shift the rack 8| carrying the unit 88 toward the unit 85 as carried by the other rack 8| there is provided on the rack 8| for the unit 88 a beveled runner |8| which engages with a roller I82 on the support 88 upon the arm 54 and this runner MI is urged into contact with the roller I82 by a coiled expansion spring I83 seated at I84 against an abutment on said support 88. When the rack 8| carrying the unit 88 is depressed by the lever 95 through its set screw 98 the runner |8I travels on the roller I82 forcing the said rack 8| with the unit 88 therein in the direction of the unit 85 on the other rack 8| against the resistance of the spring I83. This set screw 98 according to its adjustment gives the proper lay to the rack 8| having the unit 88 therein with relation to the set inclined position of the unit 85 on the closing of the unit I9 for forming the foot or base 85 when the ware I8 is rotated by the chuck I8 which is driven from the motor 23. The quantity of molten glass 91a: initially will be flattened by the closing of the unit I9 and a wiping action thereon is had thereby under the rotation of the were I8 when the chuck is turned through the motor 23. The ledge or shoulder 81 of the unit 85 functions to mold and shape the peripheral edge of the base or foot 85 dining the moldingthereof ln the operation of the machine.

An ironing or wiping action is set up by the mold units 85, 88 and I9 in the formation of the base or foot 85 when the were I8 is rotated when clamped in the chuck I8 and such base or foot will be molded or cast with a smooth polished surface devoid of ridges or rings in the formation thereof.

The ware I8 with its stem I9 when within the machine may be rotated or oscillated in a rotary direction under movement imparted to the chuck I8, the transmission mechanism 28 being regulated for such purpose and this transmission mechanism is regulated by the control handle 33 at the 'front of the machine or the stand A thereof.

The support 88 on that side having the rack 8| supporting the unit 88 has adjustably threaded therein a headed set screw I84 which plays through an elongated slot I85 in the contact 91 and the head I88 of this screw I84 regulates the incline of the unit 88 on the rebound of the rack 8| having the latter unit under the action of the spring I83 when the top mold section or unit I9 is raised as the said contact 91 will engage with the head I88 of the screw I84 and thus the'cupping of the base or foot 85 "will be had through the unit 88 and such cupping operation is arrived at through the raising of the unit I9.

The inclined disposition of the units 85 and 88 of the molding mechanism gives the proper bevel to the upper side of the base or foot 85 in v the casting or molding thereof while the unit I9 operates to shape the bottom face of said base or foot, either to cup the same or for having such surface flat or level.

It is, of course, understood that in the operation of the machine and before operation the chuck I8 is open by manipulating the lever 35 to enable the clamping of the ware I8 in this chuck. The control handle 33 will havebeen shifted to bring the transmission mechanism 28 to a neutral condition. Also the mold units for the base or foot 85 will be in open position to allow the stern I9 of the ware I8 to be embraced at the uppermost or free end of such stem by the units 85 and 88 when the same are closed with I the joining thereof with the stem I9 of the ware i8. It is, of course, understood that these units 65, 66 and 19 will have previously been adjusted to give the proper set thereto when the same are closed with relation to each other for the beveling of the foot and the shaping of the same whe being cast or molded.

Upon the molding or casting of the foot or base the chuck I6 is open and the mold units 65 and 66 are open, the mold unit 19 being opened by the action of the spring and in this fashion the ware i8 can be removed from the machine with the foot or base molded to its stem l9.

While it has been indicated that the machine in the opening and closing of the chuck and the mold units will be had by hand such operations may be mechanically carried forth and this is contemplated within the scope of the invention as fall within the appended claims.

The glassware I8 is blown with the bowl and stem prior to the introduction thereof into the machine for the molding or casting of the foot or base uponthe stem of such ware.
